This invention relates to an apparatus for v'sim-ultaneously .processinga plurality .of in dependent yarn packagesleach of which com- L prises a'hollow perforated core on which is 15 wound a quantity'of'yarn.

The .object ofthe invention is to provide `a support .for a large numberof such yarn packages and to construct the support in such a manner thatthe assemblage Vmay be 10 placed in .a suitable processing machine orremoved therefrom as a unit.

There are two `types of processingl machines in general use for treatingyarn in bulk whichislwound on a suitable beam; "1'5 One of theseycommontypes of machine is known as the vertical machine, and is adaptled toreceive the beam and to support the same in a vertical positionlwithin asuitable tank or vat, theprocessing iiuid being passed into orcirculated through the center or barrel ofthe beam, which is perforated,and outwardly through the bulk ofyarn wound on the barrel.

The second type of processing machine is asthe horizontal type machine,tand is adapted to receive and support a beam in a horizontal positionwithin, a. suitable tank 'or vat, the processing iiuid passing into theVcentral perforatec barrel ofthe beam and i530 outwardly through thebulk-offyarn wound `thereon inthe same general Vmanner asin the verticaltype machine.

In some instances the circulation of the processing fiuid is reversed,that is to say :35 the beam is submerged within the Huid and 'he iiuidis drawn inwardly through the'bulk of yarn through the perforated barreland out one en d thereof and returned to the vat or tank within whichthe beam is supported.

In some instances, especially in the hori-i zontal type machine, thebeam is adapted to be rotated. at the same time as the fluid is beingcirculated through the beam and the bulkV i of yarn thereon in orderto'more evenly disi* :I5 tribute the fiuid throughthe bulk of yarn.

This is especially desirable lin dyeingand bleaching. I

ln the beams above described the iiuid venters or leaves the barrels ofthe beam through rone .end thereof only, consequently the yarn `eralmanner as the bulk yarn beams.

at 'the' fluid-receiving or dischargingv end of the beam hasbeen shownin practice to have been processed to a greater extent than` the yarn atthe distant end of the beam.

The yarn package support forming the sub ject of the present inventionin general appearance resemblesv the beamsabove noted, 'i

differing therefrom in that a number or series of yarn packages areaxially aligned with each other on a suitable carrier and a num- P' berof these loaded carriers are supported in vand'between a pair oflaterallyspaced heads corresponding to the'end flanges of the bulk yarnbeams, thcseheads being held in rigid axial-alignment with each otherfor supporting the yarn packages therebetween.

The loaded supporting beam forming the subject of thisinvention 4isadapted to be placed in either of the types of processing machinesabovenoted and in thesame The principal object of the present inventionis tol provide the supporting beamwith means for directing theprocessing fluid into or out of Vboth ends of each alignedseries of yarnApackages at one and the same time, the

iiuid flowing` in opposite directions through each series toward thecenterVV of the series and at the same time passing radially through theperforatedV core members of the individual4 yarn p ckages and throughthel quantity of yarn wound thereon. Obviously the direction of flow maybereversed or it may alternate in the same` general manner as practicedwith the bulk yarn beams, the main point of the present invention beingthat regardless ofthe direction in which the iuid may be iiowingin themachine the said fluid will be Vowing in opposite di-v rections at ythesame .time through each series "J of yarn packages carried by thesupporting beam. The construction and Voperation'of the device will bevmore fully disclosed hereinafter,

.reference being Chad tothe accompanying drawings, of which:

Fig. lis a longitudinal sectional elevation of my .improved supporti-ngbeam taken on the line '1f- 1 of Fig. 2; .and Y een- Y taken on the line2 2, Fig. 1.

` i 1n the present instance, my improved supporting beam comprises apair of hollow heads l and 2 respectively, which, in the presentinstance, are circular in form andare supported in lateral spacedrelation with respect to eachA other on a shaft 3V which is axiallyaligned with the heads 1 and 2.l

The Vhead 1 comprises -a 'circular diskor Y plate`5 having a hub 6adaptedjtooreceive the shaft 3, the said hub being heldagainst axialmovement with respect to the shaftA between-y a pair of threaded collarsor nuts 7 and 8 respectively. Concentric with the axis ofthef shaft 34the plate 5 is provided/with an annular flange 9,'radially extendingribs 10, 10 being provided betweenthe'hub 6 and the said flange 9. y, Y-Parallel to the platev and spaced apart therefrom, by a' ring 11 is asecond plate 12 between v'whichiand vthe'plate 5 is provided a fluidspace or chamber 13. The plate 12is centrally apertured to 'receive theshaft 3 and isheld in rigid contact with the collar 7 by means of asecondcollar 14 and a nut 15, the latter ofwhich is threaded on to thethreaded portion 16'0f the shaft 3. y

The hollow head 2 y plate 25 and an inner plate 26 which is parallel toand spaced apart from the'plate' 25 by means of a-ring 27 providing afluid'sp'ace'28 between the said plates. Both of said plates arecentrally vapertured to receive the threaded end 29 of the shaft 3, theplate 26y abutting against acollar 30 secured to the said shaft 3, alcollar 31 being mounted on Ythesaid shaft at the opposite side oftheplate 26 and forming the spacer between the plates 26 and 25respectively.v Positioned on the shaft 3 at the opposite side of theplate 25'is acollar 32 Vand outside the collar 32 is afnut'33 by whichthe elements of the head f2 are Vheld in rigid relation to each other onthe shaft 3.

- Adjacent the outer peripheral edge of each of the heads 1 and 2 is "aseries of bolts or screws 34 which pass through the parallel Vplates ofwhich the respectivev heads are formed and the spacing ringsVVinterposed between the said plates. u The plates 12 and 26jof ltheheads 1 and 2 respectively areprovided with circular openings 35, 35disposed in axial alignment with Vrespect to each other and adaptedtoreceive (the respective ends of the carriers 36 on which the individualyarn packages are supported. As shown in Figs. land 2, the carriers 36are hollow and are rectangular in cross sec-` tion and are adapted toextend between the' heads 1 and 2 and'into the hollow spaces 13 and 28of the heads 1 and.2'respectively, the diameter of each of the openings35 in the measurement'across thecorners Vof the said rectangularcarriers 36,' wherebythe carriers are held against lateral movement withre.

described.

As shown infFig. 1 of the drawings, each of `the .,individual yarnpackages 00 comprises a perforated tubular core member m1 on which bers;The inside diameter of each'oflth'e perf jforated core membersw1lis,`like' the openings spectively the sai'dyarn packages Vwill be ine p axial alignment withV said openings. comprises an 'outer -is-woundafsuitable quantity of yarn m2, the` Y ysaid yarn being wound on theperforated core member toa place'substantially in a line with .theplanesof the ends of the said core mem Onthey inner face of the YplateV-12 of the hollowl head 1 is secured by riveting, bolting, oranysuitable formof fastening means, an

annular member 4() which is threaded torreceive Vthe correspondinglythreaded endvof a tube 41 which is in axial alignment with and`surrounds the shaft 3, a jam nut`42 being provided to lock the threadedend of the tube 41 in fixed relation to the hollow head 1.

On the inner face of the plate 26 of the hollow head 1 is secured asimilar plate 43'whic`h is provided with an elongated annular ange orhub 44 which is adapted to receive the. op-

posite end of the conduity 41, the elongated hub 44 providing forrelative axial movement A.within predetermined limits between the head 2and the conduit 41. e

For the lpurposeof'moving the heads 1 and 2 toward each other in orderto bring the ends of' the axially. alignedA core members mil of and 2respectively, I provide a plurality of rods 45 havingheads 46 located onthe outer each Aseries of yarn packages into abutting VContact with eachother and with the inner faces of the plates 12 and 26 of the heads 1side of the platev 5 of the head 1, the rod exl,tending through theplate 5, space 13 and plate 12 of theihead 1, thence acrossthe spacebetween the heads 1 and 2 and through openings formed in the inner plate26, the space 28 and the outer plate 2510f the head 2, the said rods 45being threaded at 47 to receive nuts 448 by whichthe said clampingmovement is Y effected. l

The rods passing throughsuitable Vopenings Vformed in the spacing members 49. ln order tomaintain the spacing members in place such times as the rods 45 maj)7 beentirelyr removed from the heads l andbolts 50, are provided which ofthe respectwe heads and the spacing mem`- hrough the plates ,13 in thehead l. The inner plate 120i the head1A is provided with a number ofopeninos 6lVv spaced around the shaft 3 and affording communicationbetween the hollow ice 1.3

oi" the head l and the interior of the conduit 4l. The inner plate 26039the head 2 is provided with a similar number of Vopenings 62 whichafford communication between the interior of the conduit'4l and thespace 28 of the head 2.

As shown in Fig. l, the shaft 3 is provided. with `pla-ne bearingsurfaces 65, at its opposite ends which are adapted to be inserted insuitable bearings in the vat or tank of the processing machine notshown).

ln order to load the supporting beam the nuts 33 and 48 are backed ofion the shaft 3 and rods 45 respectively, permitting the bead 2 to bemoved in a direction away from, the head l a sufficient distance toaccomino ,the total length of the carriers 36, the hub 44 Aot the head 2slidingo-n the conduit 4l, during such movement.

A suitable number of the yarn packages w are placed on a number of thecarriers 36 corresponding to the number of holes 35 in the heads l and 2respectively. After the carriers are .loaded in this manner one end ofeach-carrier is positioned in one of the holes 35 inthe head l, theopposite end of the carrier being aligned with the corresponding opening35 in the head 2.V After the proper number of carriers are positioned inthis `manner the head 2 is moved toward the head `l, the nuts 33 and 48being drawn-down tightly to cause the ends of the perforated cores w1 ofthe yarn packages a; to be pressed against each other and against theinner faces of the plates l2 and 26 in tight alnitting contact so thatno fluid will be permitted to escape between the adjacent yarn packagesor between the yarn packages and the supporting heads l and 2, therebycausing the fluid to pass through the yarn Wound on the said coremembers. The Vbeam having been loaded in the manner above describedisthen placed in the `processing machine with the annular flange 9 inregistry with. a suitable [fitting in the. machine through which thefluid is adapted to pass from a suitable pump by which the fluid ischine.

In the vertical type machine thisfitting is usuallylocated in thebottomV of the vat and 4the flange 9 rests in the fitting in such amanner that aseal is provided between the flange and the fitting. In thehorizontal type machine this fitting is adapted to be clamped in anysuitable way to the flangekQ to effect the desired seal therebetween andin cases where the beam is to be rotated, while circulacirculated in thema tion is taking place, the fittingwith which theilange 9 co-operatesis constructed in a manner to permitof the rotation of the flange 9 andstill maintain an efficient seal between the fitting andthe flange.

rlhe fluid is adapted to pass through the opening 60 in the plate' intothe chamber 13 in the head l, filling said chamber and passing throughthe perforation's 38 inthe ends orn the carriers 3G and through theopenings 35 in the plate l2 into the core members w1' of the yarnpackages, the fluid flowing through the perforations 38 in the carriers36 intothe core members x1 as well.

The duid also passes from the chamber 13 in the head l through theopening 6l in thc plate l2, thence through the conduit 4l and theopening 62 in the plate 26 of the head 2 into the chamber 38 in the'head2, the fluid filling the chamber 28 and passing into and through thecarriers 36 and through the yopenings 35 of the plate 26 into the coremembers acl of the yarn packages.

ln the manner above noted the fluid is being passed in oppositedirections from each ofV the heads toward the center of the beam and atthe same time flowing radially from the perforated core membersae1through the yarn :u2-wound thereon. The fluid flowing out of thepackages is collected by the tank or vat of the machine in whichthe beamis located and returned to the pump for crculation through the beam inthe manner above noted for recirculation through the beam.

Circulation of the fluid kin opposite directions through. each series ofaligned yarn packages elllects a uniform processing of cach and everyone of the `varn packages contained in the series and eliminates theirregular processing above referred to.

In order to permit a free flowing ofthe fluid through the yarn packages,it is desirableto wind the yarn packages in what is known in the tradeas open cross winding, that is each layer of thread is wound in spiralconvolutions on the core member in one direc*- tion with theconvolutions separated and the next layer is wound with the convolutionseX- tending in the opposite direction 'and separated in the same manneras the first layer.

rllhe plates l2 and 26 which come in actual Contact with the yarnpackages l-prefer to make of a noncorrosivem-etal, for example Monelmetal, and. if desired in special cases fili the entire beam maybeinademof likematerial which will not be adected bythe processing lfluidand which will not have an injurious effect upon any portions of theyarn packages coming in contact with the elementsof the beam. n i Y Inthe drawings I have shown each head as having a series ofcarrier-receiving holes '35 spaced on an outer circle concentric withthe axis of the shaft 3 and a second'series of holes spaced on an innercircle concentric with the outer circle, the outer circle having sixteenholes and the inner circle having eight holes, providing for the supportof twentyfour carriers in all. In practice I have found that eachcarrier can readily support nine packages, making the total number ofpackages to be processed in one batch, two hun-A dred'and sixteen. Eachpackagenormally is about'six inches long and about five inches indiameter. Obviously, these dimensions may vary to suit requirements andthe number of packages may be varied as desired, depending uponthenumber of packages in each aligned series and the number of seriesemployed. Obviously each carrier may support one or more packagesdepending upon the length of the package, and the number of carriers maybe varied in accordance with the diameter of the packages.
